Analysis of U.S. Patent 11,103,463: Scope, Claims, and Patent Landscape
What Is the Scope of Patent 11,103,463?
Patent 11,103,463 pertains to a method or composition involving a novel pharmaceutical ingredient or formulation. It primarily claims protection around specific chemical structures, methods of synthesis, or therapeutic applications. The patent aims to secure exclusive rights for particular biologic or small molecule compounds, as well as their uses in treating diseases.
Patent Classification and Family
- Classes: The patent likely falls under classifications related to pharmaceuticals, organic chemistry, or drug delivery systems—specifically in the US Class 514 (Drugs, bio-Affecting and body Treating compositions).
- Family members: It is probable that related patent filings exist internationally under the Patent Cooperation Treaty (PCT) or Chinese Patent Office, complementing the US patent family with similar claims.
What Are the Key Claims?
The claims define the scope of legal protection and are typically categorized into independent and dependent claims.
Independent Claims
These claims establish the core invention. For Patent 11,103,463, they specify:
- The chemical structure of the active compound(s).
- The method of synthesizing the compound.
- Specific formulations, such as dosages, delivery mechanisms, or pharmaceutical compositions.
- Therapeutic applications, such as indications for certain diseases (e.g., oncology, neurological disorders).
Dependent Claims
Dependent claims narrow the scope by adding specific features:
- Variations of the chemical structure with particular substituents.
- Specific methods of use in combination with other drugs.
- Particular formulations, such as controlled-release forms or combination therapies.
- Delivery routes, such as oral, injectable, or transdermal.
